KC9ASI can be found monitoring the CWRA and BARS repeaters. I am typically mobile, running a Radio Shack HTX-245 into a 2m 1/4 wave antenna on top of my truck.
I usually also monitor the MARA repeaters. These are not as interesting to me, for whatever reason, but prudence said that I should program all the local repeaters into the radio, and it doesn't have selective scan. I don't usually jump in on conversations, nor check into nets on the MARA repeaters, but I may answer a call if I hear one, and nobody says "HIHI" or "QSL that" to scare me off.
If you want to get a hold of me, and expect that I might be commuting, put out a call. I tend to set the radio to "scan" unless there's something interesting happening on a frequency I monitor.
